On May 11, 2007, a traffic stop on Route 116 in Franconia, New Hampshire, ended with two men dead: a veteran police corporal shot by the driver he had pulled over, and that driver shot moments later by a passing motorist who picked up the fallen officer's gun. The recording archived here is the police radio traffic that followed the shootings, not a 911 telephone call.

Cpl. N. Bruce McKay III, 48, a 12-year member of the Franconia Police Department, stopped 24-year-old Liko Kenney for a traffic violation, according to the New Hampshire Attorney General's Office. The two men had a documented history of confrontation dating back several years. When Kenney refused to cooperate and tried to drive away, McKay forced the car off the road and used pepper spray on Kenney and his passenger.

As McKay walked back toward his cruiser, Kenney drew a .45-caliber pistol and fired several rounds, striking the officer multiple times, investigators said. Kenney then drove his car over McKay.

Gregory W. Floyd, a motorist passing the scene with his teenage son, stopped and confronted Kenney, authorities said. Floyd took McKay's service weapon and shot Kenney after Kenney refused to drop his own gun. Both McKay and Kenney died at the scene. Kenney was a cousin of Olympic skier Bode Miller, whose family has long roots in the Franconia area.

After the shootings, Floyd used McKay's cruiser radio to summon help. The audio posted with this thread is that radio transmission and the dispatch exchange around it, with Floyd speaking over the officer's police radio rather than a caller reaching an emergency operator by phone. A dashboard camera in McKay's cruiser also captured much of the encounter, and the footage was later viewed more than a million times online.

The Attorney General's Office investigated the shootings and concluded that Floyd's use of deadly force was legally justified. No charges were filed against him in Kenney's death.

Floyd's own legal troubles followed. In December 2007 he threatened a neighbor in nearby Easton and was convicted of criminal threatening the next year. His conduct led the state to activate a suspended one-to-three-year sentence from a 1998 assault conviction, and he served prison time. Kenney's father, David T. Kenney, filed a federal civil-rights suit against McKay's estate, town officials and Floyd; the 1st U.S. Circuit Court of Appeals upheld the dismissal of that suit on Nov. 30, 2012.
